Exploring the Relationship of Bone Turnover Markers and Bone Mineral Density in Community-Dwelling Postmenopausal Women

Table 3

Correlations between BMD, P1NP, and CTX.

	Variables	Lumbar spine BMD		Femoral neck BMD		Total hip BMD
		Normal ()	P1NP	-0.09	0.31	-0.02	0.80	0.03	0.69
β-CTX	-0.20		0.02	-0.04	0.60	-0.11	0.20
Confirmed OP ()	P1NP	-0.15	0.002	-0.07	0.14	-0.04	0.40
	β-CTX	-0.08	0.09	-0.05	0.27	-0.14	0.004

BMD: bone mineral density; P1NP: procollagen type 1 N-terminal propeptide; β-CTX: β cross-linked C-telopeptide of type 1 collagen; : correlation coefficient. P values were obtained by Spearman correlation analysis.
